Response Elements

The stream ARN of the item where the operation stopped, inclusive of the previous
result set. Use this value to start a new operation, excluding this value in the new
request.

If LastEvaluatedStreamArn is empty, then the "last page" of results has been
processed and there is no more data to be retrieved.

If LastEvaluatedStreamArn is not empty, it does not necessarily mean that there
is more data in the result set. The only way to know when you have reached the end
of the
result set is when LastEvaluatedStreamArn is empty.
